It came with the tractor and it was a beast! I ended up selling it to Duke (METHOS). He and Allen and I met for lunch. I wanted a plug type.
I know the Cat 0 lift didn't blink at that aerator empty, but I'm not sure it would have picked it up full of water
I may sell the 782D. It's a nice tractor with front hydro ports and the Cat 0 but more than I need to mow with.
